add comma-separated DISCOURSE_HOSTNAME_ALIASES to handle multiple aliases for l…etsencrypt domain generation over env vars FIX: add letsencrypt renew location for .well-known and allow for multi-domain renewal Do not redirect to https on .well-known location for any domain so letsencrypt cert renewals can work properly. FIX: better listening for ipv6 for ipv4 only Current letsencrypt assumes ipv6 in config. Check for ipv6 before listening
